Description

The present embodiment relates to a power storage device maintenance system and a power storage device maintenance method for replacing a battery module of a power storage device.

In addition to power generation facilities that use renewable energy such as sunlight and wind power that do not emit greenhouse gases, the introduction of power storage devices for the purpose of adjusting the supply and demand of power is being promoted. The power storage device is desirably used by appropriately combining storage batteries having different characteristics such as a lead battery, a nickel metal hydride battery, and a lithium ion battery so that optimum characteristics can be obtained in accordance with usage patterns of consumers. Since the storage battery deteriorates depending on the use situation and the surrounding environment, and the capacity that can be stored decreases, it is necessary to replace the battery module of the storage device. For module replacement, it is desired to use a reusable product (used product) that is more economical than the same new product as the module being used.

For example, a storage battery reuse system includes a mechanism for predicting the life of a storage battery and notifying the replacement time, and a recycling system including a replacement service based on the information. Even if the reusable products are of the same type, the electrical characteristics differ depending on the past use conditions. Therefore, for example, there is a method of managing by classifying from electrical characteristic information and usage history information in order to facilitate reuse.

The conformity determination unit 021 executes a selection determination function that performs conformity determination based on the calculation result of the operation prediction using the conformance condition information 027. For example, the conformity determination unit 021 performs the conformity determination of the reserved battery module by comparing the calculation result of the operation prediction with the conformity condition information 027. For example, the suitability determination unit 021 determines whether the estimated remaining life value of the reserved battery module obtained as the calculation result of the operation prediction exceeds the remaining life value included in the matching condition information 027 or the remaining battery value included in the reserved battery module information 022. Compliance determination is performed by comparing whether the amount exceeds the remaining amount included in the compliance condition information 027. It is to be noted that the conformity determination unit 021 determines whether or not the operation prediction when the battery module that is not subject to replacement and the reserved battery module is operated in combination with the charge / discharge plan information 026 without using the conformance condition information 027.
